Yuav ua li cas kom paub qhov txawv ntawm T1, T2 thiab T3 tooj liab

Yuav ua li cas paub qhov txawv ntawm T1, T2 thiab T3 tooj liab

T1, T2 thiab T3 yog peb qib tooj liab. Qhov sib txawv ntawm peb qib ntawm tooj liab no feem ntau suav nrog cov hauv qab no:

1. Cov ntsiab lus tooj liab sib txawv

T1 ntshiab tooj liab muaj cov ntsiab lus siab tshaj plaws thiab tseem yog purest. T1 tshuaj muaj pes tsawg leeg: tooj liab + nyiaj CuAg: Ntau dua los yog sib npaug rau 99.95.

T2 copper refers to a copper-silver alloy, in which the copper + silver content of copper is >99.9%, uas yog, nyiaj + tooj liab + nyiaj CuAq: 2999, thiab tsis tas yuav muaj phosphorus.

Cov ntsiab lus tooj liab ntawm T3 yog, tooj liab + nyiaj CuAg; Ntau dua lossis sib npaug rau 99.70.

2. Muaj zog sib txawv

T1 ntshiab tooj liab mechanical zog tensile lub zog: ob (MPa) Ntau tshaj los yog sib npaug rau 295 elongation tom qab so: 45% ~ 50% HBS: 35 ~ 40.

T2 copper tensile strength ab (Mpa)>195, rov qab elongation: 45% ~ 50% HBS: 35 ~ 40.

T3 copper tensile strength ab(MPal:>210. Elongation tom qab so: 45% ~ 50% HBS: 35 ~ 40. Lub zog tensile ntawm T4 tooj liab yog qis dua

3. Cov khoom siv hluav taws xob sib txawv

T1 ntshiab tooj liab muaj qhov zoo conductivity, thermal conductivity, corrosion kuj thiab ua cov khoom, thiab tuaj yeem ua brazed thiab fiber ntau welded. Nws muaj cov impurities tsawg dua uas txo cov hluav taws xob conductivity thiab thermal conductivity, thiab cov pa oxygen muaj qhov cuam tshuam me ntsis rau cov hluav taws xob conductivity, thermal conductivity thiab cov khoom ua haujlwm.

T2 tooj liab muaj hluav taws xob zoo thiab thermal conductivity, corrosion kuj thiab ua haujlwm, thiab tuaj yeem welded thiab brazed. Nws muaj tsawg impurities uas txo cov hluav taws xob conductivity thiab thermal conductivity. Cov pa oxygen tsis tshua muaj kev cuam tshuam rau hluav taws xob conductivity, thermal conductivity thiab kev ua haujlwm, tab sis tuaj yeem ua rau "kab mob hydrogen".

T3 tooj liab muaj ntau impurities uas txo cov hluav taws xob conductivity thiab thermal conductivity, thiab muaj roj ntau dua T2. Nws yog feem ntau ua rau "gas kab mob" thiab tsis tuaj yeem ua tiav (annealed, welded, thiab lwm yam) thiab siv nyob rau hauv high-temperature txo cua sov.

4. Txawv tsis kam

T2 muaj qhov tsis kam tiv taus, siab tooj liab cov ntsiab lus, yog cov ntshiab, thiab muaj cov conductivity siab, thaum T3 muaj siab resistivity.

T3 zoo tib yam tooj liab ntshiab, zoo tib yam tooj liab ntshiab rau siab conductivity, yog oxygen-muaj tooj liab nrog ib tug loj feem ntawm tsis pub tsawg tshaj li 99.7% tooj liab thiab heev me ntsis impurities. Nws yog feem ntau siv hauv kev lag luam. Cov tsos yog xim liab-liab, yog li nws tseem hu ua liab tooj liab. Nws qhov kub ntawm recrystallization yog 200-280 degrees Celsius.

T3 oxygen-dawb tooj liab tsis muaj hydrogen embrittlement phenomenon, hluav taws xob conductivity, zoo ua hauj lwm, vuam kev ua tau zoo, corrosion kuj thiab tsis kub kev kawm. Ntau lub tebchaws muaj cov qauv sib txawv rau cov ntsiab lus oxygen, thiab muaj qee qhov sib txawv. OFC (oxygen-dawb tooj liab): nws yog xim hlau tooj liab nrog purity ntawm 99.995%. Feem ntau siv rau hauv cov khoom siv hluav taws xob thiab hluav taws xob xws li cov khoom siv suab, cov khoom siv hluav taws xob nqus, thiab cov cables.

Ntawm lawv, oxygen-dawb tooj liab suav nrog LC-OFC (linear crystalline oxygen-dawb tooj liab lossis crystalline oxygen-dawb tooj liab): lub purity yog siab dua 99.995% thiab OCC (ib leeg siv lead ua oxygen-dawb tooj liab): purity yog siab dua 99.996%, thiab muab faib ua PC-OCC thiab UP-OCC li al. Ib leeg siv lead ua oxygen-dawb tooj liab tsim siv UP-OCC thev naus laus zis (Ultra Pure Copper los ntawm Ohno Nruam Casting Txheej Txheem) tsis muaj kev taw qhia, siab purity, corrosion resistance, thiab tsis tshua muaj hluav taws xob impedance, ua rau cov hlau haum rau high-speed thiab zoo heev teeb liab kis tau tus mob. .

T3 tshuaj muaj pes tsawg leeg:

Copper + Silver CuAg: Ntau dua lossis sib npaug rau 99.70

Lead Pb: Tsawg dua lossis sib npaug rau 0.01

Bismuth Bi: Tsawg dua lossis sib npaug rau 0.002

Lus Cim: Tsawg dua los yog sib npaug rau 0.3 ( impurity)

T3 yog nquag rau hydrogen embrittlement hauv kev txo cov xov xwm uas muaj hydrogen, feem ntau hu ua kab mob hydrogen, yog li nws tsis tsim nyog rau kev ua tiav thiab siv los txo cov xov xwm nrog qhov kub siab tshaj 370 degrees Celsius: nws lub zog yuav nce hauv qab -250 degrees Celsius. .

T3 yog hluav taws-refined tooj liab, muaj ntau tooj liab thiab impurities. Nws muaj cov khoom siv hluav taws xob zoo, thermal conductivity, corrosion kuj thiab kev ua tau zoo, thiab tuaj yeem welded thiab brazed. T3 feem ntau yog siv rau cov khoom siv, xws li ua hluav taws xob qhib, gaskets, rivets, nozzles, thiab ntau yam conduits, thiab lwm yam. Nws kuj tseem siv rau cov khoom siv hluav taws xob tsawg dua.

Liab tooj liab tsis tas yog tooj liab ntshiab. Qee lub sij hawm me me ntawm degassing cov ntsiab lus lossis lwm cov ntsiab lus tau ntxiv los txhim kho cov khoom siv thiab kev ua tau zoo, yog li nws kuj tau muab faib ua tooj liab alloy. Suav liab tooj liab ua cov ntaub ntawv yuav muab faib raws li lawv cov khoom: zoo tib yam liab tooj liab (T1, T2, T3), oxygen-dawb tooj liab (TU1, TU2 thiab high-purity, nqus pa-dawb tooj liab), deoxidized tooj liab (TUP, TUMn ) tshwj xeeb uas muaj me me ntawm alloying ntsiab ntxiv Muaj plaub hom tooj liab (arsenic tooj liab, tellurium tooj liab, thiab nyiaj tooj liab).
